Overview#

Functions as a Service (FaaS) is where some amount of server-side logic is still written by the application developer but unlike traditional architectures is run in stateless compute containers that are event-triggered, ephemeral (may only last for one invocation), and fully managed by a third-party Service Provider.

Building an application following this model is one way of achieving a "serverless" architecture, and is typically used when building microservices applications.

Some implementations are:

Functions as a Service all use the same basic Serverless event-triggered structure consisting of:

  • Trigger - A class of event emitted by event sources.
  • Actions - Encapsulate the actual code to be executed
  • Rules - An association between a trigger and an action.
